Oil Filter Comparison for Sportsters
57-79 Sportsters
Oil filter is placed on the return line.
57-78 XL/XLH Sportsters used drop in filters (with 'horse hair' filter media) in the oil tank.
XLCH models were not factory equipped with an oil filter.
Modern drop in filter media replacements will require you to shorten the dipstick unless you find a “horse hair” type. 1)
79 models had a new oil tank with no filter.
An optional external oil filter kit (63801-79) 2) with a chrome filter could be purchased from the MoCo.
80-85 Sportsters
Oil filter is placed on the return line.
91 and Up Sportsters
- Notes:
- Champion Labs are reportedly the supplier of OEM HD filters. Champion and FRAM merged together in 2013. 12)
- FRAM Group (including FRAM® oil, air, transmission and fuel filters) has combined its filtration business with the Champion Laboratories (of UCI International). 13)
- Champion Labs manufacturers and distributes a broad range of filtration products branded under the LUBER-FINER® and CHAMP® brands.
- These businesses will now go to market as a single entity – FRAM Filtration.
- On filters with removal nuts, some have a crossed-drilled hole so racers can safety wire the filter to their bike. 14)
